PID 2264 (bash running as root) is suspicious because:

It has elevated privileges (root user).

Bash (command-line shell) is running with high CPU usage (14.0%), which is unusual unless actively being used.

If unauthorized, an attacker could be exfiltrating data via command-line methods like scp, wget, or custom scripts.

Why Not Other Options?

B (34218 - Xorg) → Xorg is a display server for GUI; no signs of exfiltration.

C (34834 - Cinnamon) → Cinnamon is a desktop environment, not a threat.

D (35963 - xrdp) → xrdp is a remote desktop service, expected behavior.

Executive management and systems administration are the most likely stakeholders to receive a vulnerability scan report because they are responsible for overseeing the security posture and remediation efforts of the organization. Law enforcement, marketing, legal, and product owner are less likely to be involved in the vulnerability management process or need access to the scan results.

The security administrator should investigate shtml.exe next, as it is a potential vulnerability that allows remote code execution on the web server. Nikto scan results indicate that the web server is running Apache on Windows, and that the shtml.exe file is accessible in the /scripts/ directory. This file is part of the Server Side Includes (SSI) feature, which allows dynamic content generation on web pages. However, if the SSI feature is not configured properly, it can allow attackers to execute arbitrary commands on the web server by injecting malicious code into the URL or the web page12. Therefore, the security administrator should check the SSI configuration and permissions, and remove or disable the shtml.exe file if it is not needed. References: Nikto-Penetration testing.

The MTTD (Mean Time To Detect) is calculated by averaging the time elapsed in detecting incidents. From the given data: (180+150+170+140)/4 = 160 minutes. This is the correct answer according to the CompTIA CySA+ CS0-003 Certification Study Guide1, Chapter 4, page 161.

Automatingthe generation of NIDS (Network Intrusion Detection System) rulesbased onStructured Threat Information eXpression (STIX) messagesis apractical use of automationin security operations​.

Option B (Privileged access requests)should involve human oversight due to thehigh risk of unauthorized access.

Option C (PKI identity verification)requires manualdocument verificationandhuman approval.

Option D (Malware analysis)often requiressandboxing and behavioral analysis, which benefit from human expertise.

Thus,A is the correct answer, asautomating threat intelligence ingestion and rule creation enhances efficiency in intrusion detection​.

The first action that should be completed to remediate the findings is to perform proper sanitization on all fields. Sanitization is a process that involves validating, filtering, or encoding any user input or data before processing or storing it on a system or application. Sanitization can help prevent various types of attacks, such as cross-site scripting (XSS), SQL injection, or command injection, that exploit unsanitized input or data to execute malicious scripts, commands, or queries on a system or application. Performing proper sanitization on all fields can help address the most critical and common vulnerability found during the vulnerability assessment, which is XSS.

Based on the compliance report, I recommend the following changes for each server:

AppServ1: No changes are needed for this server.

AppServ2: Disable or upgrade TLS 1.0 and TLS 1.1 to TLS 1.2 on this server to ensure secure encryption and communication between clients and the server. Update Apache from version 2.4.17 to version 2.4.18 or greater on this server to fix any potential vulnerabilities or bugs.

AppServ3: Downgrade Apache from version 2.4.19 to version 2.4.18 or lower on this server to ensure compatibility and stability with the company’s applications and policies. Change the port number from 8080 to either port 80 (for HTTP) or port 443 (for HTTPS) on this server to follow the default port convention and avoid any confusion or conflicts with other services.

AppServ4: Update Apache from version 2.4.16 to version 2.4.18 or greater on this server to fix any potential vulnerabilities or bugs. Change the port number from 8443 to either port 80 (for HTTP) or port 443 (for HTTPS) on this server to follow the default port convention and avoid any confusion or conflicts with other services.

The correct answer is A because SLOs — service-level objectives are measurable targets used to evaluate whether a service or process is meeting expected performance levels. When incident response is outsourced to a third party, SLOs help the organization measure whether the provider is meeting key performance expectations, such as detection time, response time, remediation time, and reporting quality.

Exact supporting extract: the Secbay CySA+ guide defines SLOs as specific, measurable targets set for the performance and reliability of a service or process. It also states that SLOs provide a framework for defining and measuring effectiveness, and that reporting on SLOs allows stakeholders to assess performance and make informed decisions.

The same guide explains that SLOs depict explicit measurements and may be set by a company or defined as part of a service-level agreement with a service provider. It also states that estimating whether SLOs are being met is a typical component of SLA management.

The official CySA+ objectives include SLOs under metrics and KPIs for reporting and communication.

Why the other options are incorrect:

B is incorrect because SLOs are performance targets, not a method for identifying hidden costs.

C is incorrect because SLOs may support risk management, but they do not directly calculate an objective risk score.

D is incorrect because risk appetite is a governance/risk-management concept, not the purpose of SLOs.

A is correct because SLOs allow the organization to measure third-party IR performance against defined KPIs.
